As with any precision basket, we recommend dialing in your grind size to achieve your desired shot time (typically 25–30 seconds for a 36g yield), as the tighter hole pattern may require a slightly coarser grind compared to a standard basket.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
